BUMP;

Specification of Letters Patent lTo.` 26,705, dated January, "To allwhom'tmay concern: 1 1

Beit known that I, WALTER PEGK, of

Rockford, county of Winnebago, in` ithe State of Illinois, have invented a new and useful Improvement in Pumps; `and I do*` hereby `declare that the `following is a full and exact description thereof, reference be# ing had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in an improved construction of double acting p force pumps for deep drilled wells as will be hereinafter more fully described.

To enable others skilled to make and use my invention, I will proceed to describe its construction and operation referring by let-` ters to the accompanying drawings forming part of this specification and in which,

Figure l, represents a side elevation of my improved pump. Fig. 2, represents a perspective elevation of the same. Fig. 3, represents a vertical sectional perspective through the center of the pump. Fig. 4, represents a cross section at line 00. Fig. 5, represents a cross section at y, y. Fig.6,

. represents a cross section `the line e, e. Fig.`

7 represents a cross section at the line o, o, and Fig. 8, represents a bottom view of upper valve and top plate of the cylinder of the pump.

Similar letters denote the same parts in the diiferent views. l

A, represents the barrel or cylinder of the pump the lower end of which is furnished with a perforated receiving or suction pipe, C, and itsupper end with a cap plate, d, in which are perforations c2, c2, (see Fig. 4) and on which is formed la stulngbox D, (see Figs. 2 and 3) through which works the hollow piston rod, B, carrying at its lower end the piston, A2.

a, a, are the steadying straps (which are fully described in another patent of which they are the subject and need not be here). E, (see Figs. 1 and 2) is a pipe communieating at its upper end with the cylinder, A,

through the apertures, c2, and at its lower va-Ive, 7c, closes and'valve, f opensgw c .l ,eem` y nd having; litsjz centra portion, e2, cutaway toleavealwaysa com munication betweengthefpipe,B, and hollow "l piston, A2. Thevalve, 0,1 which closes at" y suitable intervalsltheopenings, @2,in the top.` plate, d, has its `centralportion cut awayto. accommodate and moves upand down around ,l the hollow pipe, B, as" seen"atlllfigs..31 andlB` "l From the foregoing explanation `inwconj nection with the drawings, theconstruction,` and arrangement 3together.offthez` seyeral parts of myimproved pump3will be readily l comprehended. I will nowjdescribe itsop opening fdownward ation. n At Fig. 2, the hollow piston is justnish ing its downward stroke asthe hollowpiston 1 rod, B, begins to `ascend` carrying ywithffit the hollow piston,;A2,`the `valves,`;c, and, 1 close and, e,opens whereby alllltlfiebody` y, water contained inthe` cylinder, A, between the top, b, of hollowpistoniand thetopgcLpof cylinder is forced upthroughthe small tube or hollow piston rod, B,and out atits upper end; while at the same time the water from below the cylinderggrushesin #through th), valve, c, to fill thevacuumfproducedbyylthe ascension of the ho1lowpiston,A2. L `Wfhen` the piston has reachedytheitop ofthecylinderwio and begins to descend, fthe valve, c,`closesnip` the openings, b2, in thektopfwof piston,

b all the body of water containednfthecyl l inder, A, between itsbottom, andthe bob: $51 l tom, h, of the pistonis caused` to rushfup ,u 3 il through the small pipe or hollowipistonrod, u B. Meanwhile the valve,\c,bein`g open? the" water rushes in throughthe gop`enings,`lc2,` y. lill the vacuum produced ,inthe cylinder",1` A, p. 1,: by the descension of `the. hollow` piston; as the piston beginsto ascend `the operation `first described, is repeated and then thesec ond and so on as long asthe` piston is caused to move up and down` in thecylinder fgf When there is a sufficiency" ofwateryinl the u bottom of the well tol insurejtheconstant immersion ofthe upper valve holes,f`c2,inth top plate of the cylinder the"pipe,`E,""need* not be employed but where there is notythen llfO the side pipe, E, isnecessary` tosupplythe upper end of the cylinder, 1A, ,l y 1f,

It will be understood that my improved pump is particularly adapted to deep drilled wells, and that hence the cylinder, A, is very small, and of just Suficient leng'thto allow the stroke of the piston, while the hollow piston rod, B, may be a hundred and more feet in length.

It Will be seen from the description given Y of my improved pump that by the employment of one simple cylinder in connection With the hollow piston, piston rod, and series of valves arranged all in the cylinder as hereinbefore specied, I produce aV double acting force pump as effective as and much more simple than those novv employed while it is applicable to drilled wells of any depth. Y

Having described the'construction and operation of my improvements, I do not wish to be understood as laying claim to any new principle of operation in the pump which I have herein described but What I do claim as my improvement in pumps for drilled wells is- The construction or arrangements of the valves 0, e, f, and la, Within the cylinder, A,

in combination with the hollow piston, A2, f

and hollow pistonrrod, B, the whole constructed to operate as specified.
